Construct Activity Class

In this example, the Activity class in AndroidWidget development is very similar to the ordinary Activity, but it needs to be processed more after loading the Activity information in the trigger function.

Java code:
 
Intentintent = getIntent (); Bundleextras = intent. getExtras (); if (extras! = Null) {mAppWidgetId = extras. getInt (AppWidgetManager. EXTRA_APPWIDGET_ID, AppWidgetManager. INVALID_APPWIDGET_ID );
}
If (mAppWidgetId = AppWidgetManager. INVALID_APPWIDGET_ID ){
Finish ();
}
